| titleOfInvention | Watch exterior parts and manufacturing method thereof |
| abstract | PROBLEM TO BE SOLVED: To provide a watch exterior part made of stainless steel, Al and Al alloy, Ti and Ti alloy, brass, etc., having a high-hardness and not corroding, and having a gold color tone, and a manufacturing method thereof. To provide. SOLUTION: A hardened layer containing at least one element of Si or Ge is formed on two surfaces of Au and Fe on the surface of a watch exterior part, or Ta, Ti, Zr, A first hardened layer made of Nb or Hf nitride or carbide, a second hardened layer on the first hardened layer, two elements of Au and Fe, and at least one element of Si or Ge By forming the hardened layer, it is possible to achieve a gold-colored timepiece exterior part with high hardness that does not cause scratches due to impact and high corrosion resistance that does not cause corrosion.
